Abstract
In an optics system, a flexible mirror is deformed with an electromagnetic force. In one embodiment, an electrical current is directed through the mirror, or a conductor attached to the mirror, in the presence of a magnetic field. In one application in an adaptive optics system, the membrane mirror is used in a wavefront sensor. Deformed to oscillate between convex and concave positions, the mirror is used to alternately defocus a received light signal for determining aberrations in the light signal. By detecting aberrations in the light signal, the adaptive optics system can correct for those aberrations.
